At Datum Construction, we’re a Waikato-based building company that brings quality craftsmanship, clear communication, and down-to-earth service to every project we take on. Whether it’s a rural lifestyle build, a residential renovation, or a custom outdoor structure, we take pride in doing the job right — first time, every time.

Founded by experienced builder Ethan Williams, Datum Construction was born from a genuine love of the trade and a commitment to honest, reliable service. With nearly 15 years of hands-on industry experience, Ethan has worked on everything from large-scale rural builds to smaller residential jobs across the Waikato. He understands the value of hard work, clear timelines, and showing up when he says he will.

We're not a big franchise — we're locals, just like you. That means when you work with us, you’re dealing directly with the builder. We’re proud to serve our local communities in Te Awamutu, Cambridge, Ōtorohanga, and wider Waikato, offering a personalised service that puts your vision first.

From the initial plans to the final nail, we’re here to deliver high-quality workmanship, practical solutions, and a smooth, stress-free building experience.
